On August 30th, amateur astronomer Gennady Borisov discovered a comet beyond the orbit of Mars.

It presents no danger to Earth. It came most likely from interstellar space and to interstellar space it shall return.

Comet Borisov will make its closest approach to the sun (2 AU) around Dec. 7th. Three weeks later, near the end of December, it will make its closest approach to Earth (also 2 AU). Based on the comet's current magnitude (~18) and distance from the sun (2.7 AU), it appears to be a fairly large object — perhaps 10 km or more across, depending on the reflectivity of its surface. How bright it may become by December is anyone's guess. [The astronomical unit (AU) is roughly the distance from Earth to the Sun. Since 2012 it has been defined as exactly 149,597,870,700 metres, or about 150 million kilometres (93 million miles).]

The only things left alive after it hits will be cockroaches and Keith Richards.

A date which will live in infamy.

Should I be worried? Should I find God and set all my affairs in order before December?

Obviously not.

He just said "it presents no danger to earth" because it will miss us by 200 million miles (that's what two AUs equals roughly).

If they say it presents no danger to Earth when it arrives on December 7th, I guess I'll just have to believe them. Better than believing whatever insanity the doomsayers will come up with.

But I guess that means I'll still have to do my Christmas shopping. Rats. :?

No, actually I said that it presents no danger to Earth. A pass through comet that only comes 2 AU from earth at it closest is not a threat.

^ In case I'll just have to believe you. People on WP are usually more trustworthy, anyway. :)

Yes you can trust that cute face!

And he knows his stuff all right...

I think the comet's the one someone described as "Oumuamua's twin brother".

Just as long as there isn't another Hale-Bopp incident.

But Hale-Bopp didn't bump into us...

It made a dramatic sight in the night sky. We were camping in the mountains.

My former neighbor, and first boss, took some incredible photos of that comet against the rural landscape of northwestern Jefferson Parish, Louisiana. I have a large print he made of the Hale Bopp comet photo, amazingly visible with just a telephoto lens. Been meaning to frame it and hang it.

I meant the cult that committed mass suicide over hale-bolp.
